Aluminium Silicon Oxide Core Shell Nanoparticles (Al/SiO2, Purity: 99.9%, APS: 80-100nm)

Aluminium Silicon Oxide Core-Shell Nanoparticles

Aluminium Silicon Oxide core-shell nanoparticles are a class of nanomaterials that consist of a core made of aluminum (Al) surrounded by a shell of silicon dioxide (SiO₂). These nanoparticles combine the unique properties of aluminum—such as high reactivity, excellent conductivity, and light weight—with the stability, insulating nature, and biocompatibility of silicon dioxide.

Applications:

Pollutant Removal and Water Treatment: The adsorption properties of Al/SiO₂ core-shell nanoparticles can be utilized for removing heavy metals, organic pollutants, or contaminants from water or air. The SiO₂ shell allows for the functionalization of the nanoparticles with specific ligands that can selectively bind to pollutants, while the aluminum core can help enhance the adsorption capacity.

Catalysis for Environmental Remediation: Al/SiO₂ core-shell nanoparticles can serve as catalysts in processes aimed at pollutant degradation or carbon capture. The combination of the aluminum core’s reactivity and the SiO₂ shell’s stability can help promote reactions that break down pollutants or capture carbon dioxide from industrial emissions.

Optical and Sensing Applications

Optical Sensors: The Al/SiO₂ core-shell nanoparticles can be used in optical sensing applications, such as in surface plasmon resonance (SPR) sensors or fluorescent sensors. The core-shell structure allows for tunable optical properties, which can be tailored for specific sensing applications like detecting gases, pH changes, or biomolecules.

Surface-Enhanced Raman Spectroscopy (SERS): The aluminum core, combined with the SiO₂ shell, can enhance the Raman scattering of molecules adsorbed on the surface of the nanoparticles, making them ideal for SERS-based biosensors or chemical sensors.

Aerospace and Automotive Industries

Lightweight Materials: Aluminum’s lightweight and high strength-to-weight ratio make it an attractive material for use in the aerospace and automotive industries. Al/SiO₂ nanoparticles can be used to develop composite materials that are both strong and lightweight, which can be employed in components like aircraft parts or vehicle bodies to reduce weight and improve fuel efficiency.
